(54) Photosensitive material for electrophotography


(57) Disclosed are a photosensitive material for the electrophotography, which comprises an electroconductive substrate and a photosensitive layer formed on said substrate, said photosensitive layer comprising a charge transfer medium and a charge-generating pigment dispersed in said medium, wherein the photosensitive layer contains as the matrix resin a thermoplastic polyester consisting essentially of recurring units represented by the following general formula:

wherein R' stands for a phenylene group or an ethylene group, R2 stands for a group represented by the formula

or-

R3 stands for a direct bond or a divalent bridging atom or group, and the ring A may have a substituent not participating in the reaction,

and a photosensitive material for the electrophotography, which comprises an electroconductive substrate, a photoconductive organic pigment-containing, charge-generating layer formed on said substrate and a charge transfer layer formed on said charge-generating layer, wherein the charge transfer layer contains as the matrix resin the above-mentioned thermoplastic polyester.
